Charge Smarter, Not Harder


No reason to rehash #BatteryGate, but the company's new "Optimized Battery Charging" feature is certainly a response to the controversy. 

"A battery’s lifespan is related to its chemical age, which is more than just the length of time since the battery was assembled," Apple writes on its website."As lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in reduced battery life and reduced peak performance."
Optimized Battery Charging was introduced last fall with the debut of iOS 13. It supposedly reduces wear-and-tear on the battery by delaying charging past 80 percent. On-device machine learning algorithms learn your charging habits so that the feature only kicks on when your iPhone thinks it'll be plugged in for an extended period of time, like overnight.
The aim is to give you a full battery when you do finally unplug, so if you typically wake up at 8 a.m., Optimized Battery Charging will juice up that last 20 percent of the battery just before you wake.
This setting is turned on by default when you update to iOS 13. To turn it off, go to Settings > Battery > Battery Health > Optimized Battery Charging.

Customize Your 'Do Not Disturb' Gates

With a parent who's been a loyal Do Not Disturb user for years, I've had a number of minor emergencies where I couldn't reach her. No, she still hasn't turned off Do Not Disturb, but she has added me to a list of contacts that can breach its ironclad gates. If you'd consider them an emergency contact, you should consider adding them to that list. Find the desired person in  Contacts  > Tap  Edit  in the top right corner > On the edit page, click either  Ringtone or Text Tone > At the top, you'll find  Emergency Bypass , which will allow sounds and vibrations from that person even when Do Not Disturb is Enabled. You may want to select a quiet ringtone if you choose to do this—after all, not every text and call after bedtime is a dire emergency.

Introduction

After 12 years of the iPhone, it's no longer a novelty—and neither are most of the "hacks" that you'll find online. You probably already know that you should close out your background apps for faster performance or that you can put the device into Airplane Mode to charge it up more quickly.  Here's something you may not have considered, though: with every operating system update comes new hidden tricks. Last September, iOS 13, the latest software, introduced some fancy new features like Dark Mode on all devices, but as with previous software rollouts, there are some covert Easter eggs to discover.

The Cursor Is Easier to Move When Editing Text

Image
Before, whenever you needed to move the cursor, you could tap-and-hold to bring up the magnified view, then drag to where appropriate. The magnifier was kicked to the curb in iOS 13, so now you just grab the cursor and move it without much thought. Some have found the change a bit annoying, since your finger basically blocks the cursor.
